To a/ZZ whom ,it muy concern:

Beit known that I, EVELYN 1P. SPERM?, a citizen of the United States, residing at Oak Park, in the-county `ofCook and Statelof Illinois, have invented certain new and useful Improvements Floor-Supports -for Build- My invention relates to that class of flooring or floor-'supports com rising metallic cracking of the concrete above the metallic floor-beams upon which the sleepers rest.

The principal objectfof my invention is to provide a simple, economical, and efficient floor-support or flooring for buildings.

for' preventing the cracking of the concrete m A further object of the invention is to provide in a flooring for buildings metallic floorstrips or sleepers adapted to be embeddedin 1 and held in place by the concreteand to permit the-fioor-nails to be driven into 'and securel `held in place thereby. A liirtherobj ect of the inventin is to provide in a floor-support or i'looring for buildings suitable means for preventing the cracking of the concrete which is supported by the metallic floor-beams.

Other and furtherobjects of the invention will appear froman eXaminationo the drawings and the following description and claims.v Y

` The invent-ion consists in a licor-support or iiooring having metallic iioor-strips or sleepers embedded concrete and provided with flanged side members adapted Vto securely hold vthe Hoor-nails, so as to dispense with wooden tuning-strips. f

It consists, further, a floor-su port havin metallic floor-beams provided) with meta 'lic floor-strips or sleepers resting thereon and embedded in the concrete and means by reason kci: the eX ansionand contraction of the metallic loor-y earns due to variations 5o in temperature.

n consists, further and-Lemmy, in the Yfattion hereinafter described and claimed,

In the accompanying drawings, Figure 11 'is a sectional elevation of a ,-'portion :of a 'floor and floor-support constructed in accordance with my improvements ,Fig 2, a view elevation, ta'kenonline 2 of Fig. '1 looking lin tures, combinations, 'and l'details of 'construethe direction 4of the arrow, and Fig-3 afdetail view showing one of the, metallic iioo'r-stri'ps or sleepers -to which vthe floor properis secured. Y

In constructing a floor .provided with my improvements a plurality of metallic floorbeams a, preferably in 'the for'rnoi I-beams, is 'laid in the ordinary manner in position 5to support the weight of the'flooringimembers which rest thereon.

intervals, and vas they are 'all preferably ofidentical construction 'and ythe manner'ofllaying them is well knownit is onl deemed necessary lto herein illl'is'trate lan' describe one of such beams. v

Metallic iioor-strips b are arranged 'at right angles to and rest upon the 'metallic Hoor-'beams at suitable intervals throughout the entire area-0f the floor. rll-heise metallic floor-beams or sleepers are each formed `o'f 5a pair of side members ysecured together by means of rivets t. Bottom flanges-. e, Ipreferably integral with the. yside members, eX- Y tend outward laterally therefrom 'and rest The upper loosely upon the floor-beams. l edges of the side members, which `form the licor-,strips or sleepers, are provided'with'outwardly and downwardly hentay-integral portions or Hang-es d in 'the ferm ofelongated fer' `partially-'lattened beads, 'such :flanges "extending from end toA 'end of' the floor-stripsand forming spaces@ between 'the outerilolds and inner web or side portions.

These `I-'beams are :laid Y in parallel relation to each other-fat suitable' The floor-strips may beformed fin sections f lth'e Aends of which are secure-d together by. f

means ofvmetallicrodsf, as shown Figs. t

land'Z, rods-extend into the spaces formed by the beads ofthey joined end por? y tions ofthe sleepers-'and 'securely-hold the Iper edges thereof in position. The lower edges of the floor-strips are secured by-means i of UI-'sha'pedmetallic clilps g, as shownin-Figs. l. I and 3. These 'metar he. @lips are meenten upon the laterally-extending bottom iianges of the strips at the joined end portions thereof and extend across the joint, so as to see curely hold them together. The space between the Hoor-strips or sleepers is filled with concrete h, and wherever it is desirable to mount conduits in such concrete, which eX- tends above the bottom of the hoor-strips, the loorestrips are cut away, as shown at i in Fig. 1, thus permitting the mounting of a conduit in the concrete, as shown. The hoor-boards 7c are laid upon the metallic floor.- strips or sleepers above described and are also supported in part by the concrete. These boards are secured to the floor-strips or sleepers by means of nails Z, driven downward, preferably at an incline, between the metallic side members of the floor-strips and securely held in place thereby. Ihev outwardly and downwardly folded integral portions of the metallic side members provide additional rigidity for the iioor-strips. Sufficient .space is formed between the side members, however, to permitv the 'floor-nails to be driven into securing position between such side members and securely held between the beaded upper edge portions thereof.

In order to provide suitable means for preventing the concrete from cracking at points above the metallic floor-beams, a thin layer of non-adhesive material m, preferably paper, is laid upon the upper surface of each of the metallic beams before the concrete is laid. The concrete is then laid and allowed to harden in the usual manner.

By the above 'arrangement it will be seen that the metallic floor-strips are laid loosely upon the iloor-beams and held in place by means of the concrete in which the laterallyk extending flange portions of the iioor-strips are embedded. The clips which secure the endsof the sections together are also held in place by the concrete and may be riveted to the flanges of the floor-strips, if desired. The upper folds or elongated beads of the iioorstrips supply the needed rigidity to securely hold the floor-nails when driven therebetween and, with the rod members f, provide means for securing the upper edges of the adjacent end portions together. The rivets whichk connect the side members ofthe strips are adapted tolpermit a sufficient space to be formed between the side members to admit the nails, which are securely held in place, so as to dispense with the necessity of employing wooden furring-strips between the metallic members. By this means a flooring is provided which is entirely ireprooi, and the Hoor-boards are held securely in place.

I claim- .l

In a device of the class described, a floorstrip formed of metallic side members provided with lateral bottom ilange portions and having integral outwardly-folded upper portions, and means for securing such side meme bers together in engagement with the opposite sides of floor-nails driven therebetween.

2. In a device ofthe class described, a floorstrip formed of parallel metallic side members provided with lateral bottom ilange portions and having integral upper outwardlyfolded portions forming longitudinal openings, and means for securing such parallel side members together in engagement with the opposite sides of Hoor-nails driven therebetween.

In a device of the class described, the combination of a plurality of Hoor-strips mounted end to end, each formed of parallel metallic side members having upper outwardly-folded portions forming longitudinal openings for receiving a connecting-rod, and a connecting-rod mounted in such openings and connecting the adjacent end portions of such AHoor-strips.

4. In a device of the class described, the combination of a plurality ol hoor-strips mounted end to end, each formed of metallic side members having lateral bottom [ianges and upper outwardly-folded portions forming longitudinal openings, connecting-rods mounted in such longitudinal openings and connecting the upper end portions of such floor-strips, and metallic clips mounted upon the bottoni langes and connecting the lower end portions of' such strips.

5. In a device of the class described, the combination of a plurality of floor-stri )s mounted end to end, each formed of metaliic side members having outwardly-folded upper portions, said side members being secured .together and provided with a siace therebetween or receiving lioor-naiis, cement in which suoli floor-strips are embedded, and means for supporting such floor-strips and the cement in which they are embedded.

6. In a device of the class described, the combination of a plurality of ioor-stri ps, each formed of metallic side members having outwardly-folded upper portions and having lateral bottom flanges, cement in which such laterally-hanged floor-strips are embedded,
